# ELF: Embedded Language Flows

This repository contains pre-tokenized datasets used in the paper [ELF: Embedded Language Flows](https://huggingface.co/papers/2605.10938).

ELF is a class of diffusion models in continuous embedding space based on continuous-time Flow Matching. The datasets provided here are pre-tokenized using the T5 tokenizer and encoded using a frozen T5-small encoder as described in the paper.

## Dataset Details

The authors provide pre-tokenized splits for several benchmarks:
- **OpenWebText**: Used for unconditional generation.
- **WMT14 De-En**: Used for machine translation.
- **XSum**: Used for abstractive summarization.

## Usage

You can load the pre-tokenized datasets directly using the Hugging Face `datasets` library:

```python
from datasets import load_dataset

# Example: Load the OpenWebText pre-tokenized dataset
dataset = load_dataset("embedded-language-flows/openwebtext-t5")

# Example: Load the WMT14 De-En validation set
dataset_val = load_dataset("embedded-language-flows/wmt14_de-en_validation_t5")
```
